In the practical operation of my improved cigarette-machine, the tobacco is fed by hand from the feed-boardB into the spout C, through which it descends into the revolving feeder D, which revolves in the direction indicated by the arrow in Fig. S. The feeder D consists of a rotating chamber or receptacle, arranged to revolve on the shaft V, which is supported in `journals on a suitable framing, d', and which chamber maybe either conical, cylindrical, or, as represented in the drawings, spherical, with hat ends. One ofthe ends ofthe feederis open, (see Figs. 5 and 6,) except as it is crossed by the spokes V, for the purpose of permitting the passage of the tobacco into the chamber from the spout C. The open end is provided with a cover, U, Fig. 7, by which the escape of the tobacco from the feeder is prevented. The feeder is divided into two parts by a narrow circumferential opening, fv, Fig. 6, into which the teeth E of the endless chain F project on the under sidehas represented in Fig. 16. rIhe edges of the feeder on each side of the opening c are provided with a row of pins or points, q, which project inward from the interior surface ofthe feeder on each side of the opening, and are inclined toward each other, as represented in the drawings, so that as the feeder revolves the points q q nearly touch the teeth E E. rIhe opening c is closed except where the teeth E project into it by the band n, which is supported by bracing from the framework or the table I in any convenient manner. rIhe band n has attached to it the scraper r, Figs. S, 10, and l0, which projects downward into the upper part of the feeder, and performs the office of scraping or detaching the tobacco from the points q q. The operation of the feeder in delivering the tobacco to the feeding-teeth E on the endless chain F will be understood from an examination of the sectional view, Fig. 8. The feeder is driven at a sufiicient speed to give the tobacco therein a tendency to Hy outward from the action of centrifugal force, and, as the .feeder revolves, the tobacco is continually tossed about and eommingled within the feeder, thereby insuring a regular delivery to the teeth E.` The tobacco is stripped or detached from the points q q at the upper part of the feeder by the scraper r being thrown downward thereby.

Ihe teeth E, projecting into the opening o and moving in a direction opposite to that in which the feeder revolves, pull a regular supply of tobacco out from the lower side of the feeder through the opening o and into the former 11, by which the tobacco is shaped and compacted into a rod, which is inclosed in a paper tube, and cut into suitable lengths' by the subscquent operation of the machine.

Ihe wheels G and H, about which the endless chain F travels, are supported by suitable journals arising from the bed A, the wheel H being driven from G by the chain. Between the two wheels the chain F is supported by a table, I, which is provided on its upper side with a groove, m, in which the chain travels. The table I supports also the former b, the trimming-wheel c, and the compressor d. The former b consists of a curved plate of metal, largest at the end next the feeder, and tapering gradually toward the trimming-wheel. It is fastened to the table I in any convenient manner. The trimming-wheel c is a hardenedsteel roller, having a groove about its periphery of a size corresponding to that of the compacted tobacco rod. It is supported on the table I by suitable journals.A The trilnmingwheel, the edges of which are sharp, projects downward into the groove a in the chain F, and it trims oft` any surplus tobacco from the rod. The compressor d, the form of which is shown in the detached views, Figs. 20 and 21, projects downward into the groove c in the chain, and serves by pressure to compact the tobacco rod after it has passed the trimmingwheel. The colnpressor is provided with wings by which it is afiixed to the table I.

The endless chain F consists of a series of links connected together at their ends by screws or pivots, and adapted to travel around the wheels G and Hin suitable grooves formedin their peripheries. The links are provided with a groove, a, in which the tobacco rod is formed. rlhe links are perforated with holes in the middle of the groove a, through which the movable feeding-teeth E pass. The teeth are preferably formed of bent pieces of wire, which are pivoted to the sides ofthe links at e e', Fig. 13, on pins or screws inserted into the links. The wire forming the teeth eX- tends along the sides of the links, is then bent inward under the links, and passes upward through the openings, so as to project for a short distance above the links. At s, Figs. 13 and I4, the wire is bent on itself sharply, so as to form a lug or projection which engages with the inclined guide Z, which projects inward from the side of the groove in the table I, and operates to control the position of the teeth relatively to the upper side of the links. As the teeth traveling with the chain F pass through the opening c aboutthe periphery of the feeder D, they carry the tobacco with them into the former 11,' but it is necessary theyy should be withdrawn from the tobacco rod as the latter passes away from the feeder., This operation is effected by the inclined guide Z,V which draws the teeth E downward as they IOO IIO

- detached views, Figs. 22 and 23.

pass by it into the position represented by the dotted lines E', Fig. 13, when their ends are free from the tobacco, having moved down to or below'the bottom of the groove a in the links. The operation will be readily understood from the sectional view, Fig. l5.

In the drawings I have represented that part ofthe feeding-teeth E which passes through the chain as slightly bent on a circle having its center' of curvature at or near the Vpivotal point e of the teeth; but it is obvious that the teeth may be made straight if the openings in the chain are slotted for this purpose; or, if the teeth be arranged to move radially in and out, like the action of the sliding rods of my former patent, No 231,947, the groove'in the wheel H is so formed as to press the teeth out through the chain, and, after being engaged with the tobacco, the teeth will remain therein without any tendency to drop downward, although, if necessary, the guide Z may be made double, the lugs s passing through between the upper and lower portions thereof, for the purpose of positively preventing the teeth from falling down out of the tobacco. As the teeth arrive near X, on the lower side of the wheel G, they fall downward, from their own weight, and project outward from the chain.` Only the points of the teeth E are represented in Fig. 8.

The formed tobacco rod is removed from the groove a in the chain by means of the scraper e, Fig. 8, which is supported from the bed A by a suitable arm. Provision may be made for adjusting the position of the scraper relatively to the chain in any suitable manner. The form of the scraper is represented in the It is provided with a groove on its upper side, through which the formed `tobacco rod passes. After the scraper, the tobacco rod neXt passes over the table f, on which it is supported While the web of paper is folded about it. The paper web, which is coiled on thedrum h, Fig. 2, passes around the -roller j, one of its edges being covered with paste by the paste-roll t' at this point, and thence around the rollerik, whence it passes onward in the same direction in which the tobacco rod t is traveling, being folded about the said rod as it moves over the table f by the operation of the folders g and g', Fig. 3. Detached views of the folders are' given in Figs. 4 and 1l, from which and Fig. 3 their action in folding the paper about the tobacco will be readily perceived. The operation of folding the paper web about the tobacco rod is very much facilitated by placing the folders at some little distance apart on opposite sides of the rod-say, from one to two inches; but this arrangement necessitates the support of the rod between the folders and preferably for some short distance in front of the first folder. For this purpose I use the table or support f, which sustains the rod at vand between the folders After the fold is completed by the second folder, g', and the' pasted edges of the web caused to adhere, the

'cigarette rod will support itself. From the and deliver it to the knife K, to be severed c into suitable lengths. These rollers are provided with grooves of a suitable size to feed the cigarette rod, and they are supported from the bedplate A by suitable framing, being geared together to run at the proper speed, and driven from the main driving-shaft L by the belt P, Fig. l. The knife K revolves with the shaft Y, being driven from the shaft of one of the rollers J by the bevelhgear Z at a suitable speed to cut off cigarettes from the cigarette rod of the proper length. The knife K divides the cigarette rod at each revolution against the stationary shear-block, T.

Ihe band n encircles the feederD at aslight distance therefrom, so as to prevent the escape of any tobacco through the opening V, wlthout producing unnecessary friction on the exterior of the feeder. The band a is slotted at its lower part to permit the passage of the feeding-teeth E, as represented in the drawings, Figs. 6 and 16.

Ihe groove about the wheel H, in which the chain travels, is shaped so as to press the teeth E outward, while the groove in the wheel G is of a form which permits the teeth to pass around the wheel when their points are withdrawn below the bottom of the groove a.

I do not claim herein anything which has been previously patented to me.
